IMPROVEMENT IN REVERSIBLE VKNOB-LATCHES.

The Schedule referred to in these Letters Patent and making part of the same.

' I, HENRY M. RITTER, of Cincinnati, county of Hamilton, and State of Ohio, have invented certain Improvements in Reversible Latchcs, of which the following is a specification.

The nature of my invention consists of an improvement in the catch-lever A,-having a tail-piece extending nnder the holding-screw, or other device, provided with a beveled catch, c, and projection f, whereby simplicity of construction and convenience of operation are combined, and of which the following is a description, the letters and gures on the drawing accompanying this specification referring to the same parts. l

Figure 1 is a plan of the latch when in Working position.

Figure 2 isa plan of the latch when in a'position to be reversed. l

Figures 3, 4, 5, and 6 are parts of the latch removed from the case.

A. tig. 1, a catch-lever, having a tail-piece extending under the holding-screw, or other device, to prevent the latch from being reversed when in working order, and carrying on itscnd a projection, f.

. The catch-lever A is also provided with a beveled catch at c, byv which it operates the latch by the yoke B when acted upon by the hub I).

B is the yoke, into which the latch G is screwed or swiveled, so as to admit of rotation. 4

D is the hub, by which the yoke B and lever A are operated by the horns c e, which, when forced against the projections f and f on yoke B and lever A, draw back the latch.

The operation of reversing the latch is performed by holding the lock with the 'side H downward and pressing back the latch, when the lever.A will fall of lits own gravity, and allow the latch to be .thrown forforth. HENRY M. RITTER.
